WebPoly(methyl methacrylate) (PMMA) is usually obtained by the addition polymerization of methyl methacrylate (MMA) (Fig. 1). In the middle of the 1930s, ICI Acrylics (now Lucite … WebAt this ratio, an increase in the band strength of the methyl methacrylate v(C=0) vibrations is also observed. The most plausible explanation of the obtained anomalies in the polymerization of methyl methacrylate in pyridine (6.215–7.991 mole/liter) is the formation of a weak complex which affects the initiation step.
Given the scale of production, many methods have been developed starting from diverse two- to four-carbon precursors. Two principal routes appear to be commonly practiced. The compound is manufactured by several methods, the principal one being the acetone cyanohydrin (ACH) route. ACH is produced by condensation of acetone and hydrogen cyanide. The cyanohydrin is hydrolyzed in the presence of sulfuric acid to a sulfate ester of the methacrylamide. WebAug 12, 2024 · For example, nanocrystal PI-assisted photopolymerization of methyl methacrylate (MMA) was demonstrated on a zinc oxide surface . Photon excited electron-hole pair generation in semiconductor PIs with a slow recombination step and homogeneity in the system enables rapid polymer formation.
